When I woke up this morning, I thought: my eye feels so weird I bet I'll visibly see something. I looked in the mirror, and saw something like the dotted region above. Note that I'm opening both eyes wide.
This swelling seemed to reduce during the day, but now that I took a nap this evening, it's back.
I'd like a service that I can send pictures like this to that will tell me what's wrong, and if this is something to worry about. This is not my idea, and in fact, a friend of mine has in the past sent a picture of sorts to a doctor to diagnose, but they happened to know the doctor.
